Preheat oven to 350°F. In a bowl, mix graham cracker crumbs, ground pistachios, and sugar. Stir in melted butter until crumbs are evenly moistened. Firmly press the mixture into the bottom and slightly up the sides of a 9-inch springform pan. Bake for 5 to 8 minutes until lightly fragrant, then cool to room temperature.

Reduce oven temperature to 285°F. In a large bowl, blend cream cheese, sugar, sour cream, heavy cream, salt, and vanilla with an electric mixer on medium-low until smooth and creamy. Add pistachio paste and combine thoroughly. Sift in cornstarch and mix well, scraping down sides. Lightly beat the eggs and add, mixing just until incorporated.

Pour filling over the cooled crust and tap the pan to remove air bubbles. Bake for approximately 60 minutes, or until the edges are set but the center wobbles slightly. Leave the oven door ajar and let the cheesecake cool inside for 1 to 2 hours to prevent cracking.

Once cooled to room temperature, cover the cheesecake tightly with plastic wrap and refrigerate for at least 5 hours or overnight for best texture.
